Question

An angle measures 158.2° less than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

the 2 angles are 169.1° and 10.9°

Explanation:

Supplementary angles add to 180

x = first angle

y = second angle = x - 158.2

x + y = 180

x + (x - 158.2) = 180

2x = 180 + 158.2

2x = 338.2

x = 338.2/2 = 169.1

y = 169.1 - 158.2 = 10.9

x + y = 169.1 + 10.9 = 180
